Micropeptides and use thereof for modulating gene expression

ABSTRACT

Process for detecting and identifying micropeptides (miPEPs) encoded by a nucleotide sequence contained in the sequence of the primary transcript of a microRNA and use thereof for modulating gene expression.

FIELD OF THE INVENTION

The present invention relates to micropeptides (peptides encoded bymicroRNAs or “miPEPs”) and use thereof for modulating gene expression.

BACKGROUND OF THE INVENTION

The microRNAs (miRNAs) are small non-coding RNAs, about 21 nucleotidesin length after maturation, which control expression of target genes atthe post-transcriptional level, by degrading the target mRNA or byinhibiting its translation. The miRNAs occur in plants and animals.

The target genes are often key genes in developmental processes. Forexample they encode transcription factors or proteins of the proteasome.

The regulation of expression of the miRNAs is very poorly understood,but it is known in particular that the latter involves, like most codinggenes, an RNA polymerase II: this enzyme produces a primary transcript,called “pri-miRNA”, which is then matured by a protein complex inparticular containing the Dicer type enzymes. This maturation leadsfirstly to the formation of a precursor of miRNA called “pre-miRNA”,having a stem-loop secondary structure containing the miRNA and itscomplementary sequence miRNA*. Then the precursor is matured, whichleads to formation of a shorter double-stranded RNA containing the miRNAand the miRNA*. The miRNA is then manipulated by the RISC complex, whichcleaves the mRNA of the target gene or inhibits its translation.

Moreover, it has been shown that the presence of introns in the primarytranscript of the microRNA increases the expression of the maturemicroRNA (Schwab et al., EMBO Rep., 14(7): 615-21, 2013). However, owingto experimental difficulties, the primary transcripts of microRNAs, orpri-miRNAs, have received very little study.

About 50% of eukaryotic genes have small open reading frames withintheir 5′UTR region (5′ UnTranslated Region) upstream of the codingsequence. These small open reading frames (or “uORFs” for upstream ORFs)may perform a role of translation regulator, mainly in cis, bymodulating the fixation and the rate of the ribosomes on the mRNA, butalso in trans by an as yet unknown mechanism, by means of peptidesencoded by said uORFs (Combier et al., Gene Dev, 22: 1549-1559, 2008).By definition, the uORFS are present upstream of coding genes.

Recently, small ORFs have also been discovered in long intergenicnon-coding RNAs (lincRNAs), the putative function of which, if itexists, is not known (Ingolia et al., Cell, 147(4): 789-802, 2011;Guttman & Rinn, Nature, 482(7385): 339-46, 2012).

However, no example has yet been reported concerning the existence ofORFs encoding peptides within non-coding microRNAs. Until now, themicroRNAs, and by extension their primary transcript, have always beenregarded, based on their particular mode of action, as non-codingregulatory RNAs that do not produce any peptide.

SUMMARY OF THE INVENTION

One of the aspects of the invention is to propose peptides capable ofmodulating the expression of microRNAs.

Another aspect of the invention is to propose a means for modulating theexpression of one or more target genes of a microRNA.

The present invention offers the advantage of allowing easier and moreeffective control of the expression of genes targeted by the microRNAs,through a means other than the microRNA.

The invention thus relates to a process for detecting and identifying amicropeptide (miPEP) encoded by a nucleotide sequence contained in thesequence of the primary transcript of a microRNA, comprising:

-   -   a) a step of detecting an open reading frame from 12 to 303        nucleotides in length contained in the sequence of the primary        transcript of said microRNA, then    -   b) a step of comparison between:        -   the accumulation of said microRNA in a specified eukaryotic            cell expressing said microRNA,        -    in the presence of a peptide encoded by a nucleotide            sequence that is identical or degenerate relative to that of            said open reading frame, said peptide being present in the            cell independently of transcription of the primary            transcript of said microRNA, and        -   the accumulation of said microRNA in a eukaryotic cell of            the same type as the aforesaid specified eukaryotic cell            expressing said microRNA,        -    in the absence of said peptide,            in which a modulation of the accumulation of said microRNA            in the presence of said peptide relative to the accumulation            of said microRNA in the absence of said peptide indicates            the existence of a micropeptide encoded by said open reading            frame.

The invention relates in particular to a process for detecting andidentifying a micropeptide (miPEP) encoded by a nucleotide sequencecontained in the sequence of the primary transcript of a microRNA,

comprising:

-   -   a) a step of detecting an open reading frame from 15 to 303        nucleotides in length contained in the sequence of the primary        transcript of said microRNA, then    -   b) a step of comparison between:        -   the accumulation of said microRNA in a specified eukaryotic            cell expressing said microRNA,        -    in the presence of a peptide encoded by a nucleotide            sequence that is identical or degenerate relative to that of            said open reading frame, said peptide being present in the            cell independently of transcription of the primary            transcript of said microRNA, and        -   the accumulation of said microRNA in a eukaryotic cell of            the same type as the aforesaid specified eukaryotic cell            expressing said microRNA,        -    in the absence of said peptide,            in which a modulation of the accumulation of said microRNA            in the presence of said peptide relative to the accumulation            of said microRNA in the absence of said peptide indicates            the existence of a micropeptide encoded by said open reading            frame.

The mutated pri-MtmiR171b is therefore incapable ofproducing MtmiPEP171b1. The error bar corresponds to the standard errorof the mean (number of individuals=30). It is noted that the absence oftranslation of MtmiPEP171b1 leads to a marked decrease in theaccumulation of miR171b.

The error barcorresponds to the standard error of the mean (number ofindividuals=30). The overexpression of MtmiPEP171b1 or application ofmiPEP171b1 increases the accumulation of pri-MtmiR171b (A),pre-MtmiR171b (B) and MtmiR171b (C).

The error bar corresponds to the standard error of the mean (number ofindividuals=30).

In both cases, it is noted that the expression of miORF, and thereforethe production of miPEP, leads to an increase in the accumulation ofpre-miRNA.

The photograph shows two plants of the same age: a control plant (planton the left) and a plant treated with AtmiPEP165a (plant on the right).The treatment with AtmiPEP165a leads to a phenotype with greatlyaccelerated root growth in Arabidopsis thaliana. The graph shows theexpression of pre-miR165 in response to treatment with increasing dosesof AtmiPEP165a.

Thex-axis indicates the origin of the miPEP, i.e. the Drosophila species.It is noted that despite a significant change in their size (by morethan a factor of 3), the charge of the miPEPs is still very basic (>9.8)in the 12 species studied.

FIG. 15. Effect of the addition of sequences on the function of miPEP.

The tobacco leaves were transformed in order to overexpress miPEP171b.These graphs show that the addition of sequences (tag His, HA or GFP)does not alter the function of miPEP.

The roots of Medicago truncatula were transformed in order to expressfusions between GUS protein (in blue) and the promoter of miR17b (A, E),the ATG of miPEP171b1 (B, F), whole miPEP171b1 (C, G) or ATG2 (secondATG located on the precursor, after miPEP) (D, H). It is clear thatthere is expression of miRNA in the root tips (A) as well as the lateralroots (E). The transcriptional (B, F) and translational (C, G) fusionsshow an expression of miPEP171b in the same tissues, whereas the nextATG is not active (D, H).

The y-axis indicates therelative expression of Pre-miR8. The error bar corresponds to thestandard error of the mean (number of independent experiments=6). It isnoted that the expression of DmmiPEP8 increases the expression ofDmmiR8, and this effect is linked to the translation of the mRNA.

FIG. 18. Impact of DmmiPEP8 on accumulation of DmmiR8 in cells of D.melanogaster

The cells of Drosophila melanogaster were transfected in order tooverexpress wild-type DmmiR8 (OE miR8) or DmmiR8 the translation startcodons of which have been mutated (OE miR8 miPEP8 mut). The y-axisindicates the relative expression of Pre-miR8. The error bar correspondsto the standard error of the mean (number of independent experiments=2).It is noted that the presence of DmmiPEP8 increases the expression ofDmmiR8.

FIG. 19. Impact of HsmiPEP155 on accumulation of HsmiR155 in cells ofHomo sapiens

HeLa cells of Homo sapiens had been transfected in order to overexpressHsmiPEP155 (OE miPEP155). The y-axis indicates the relative expressionof Pre-miR155. The error bar corresponds to the standard error of themean (number of independent experiments=2). It is noted that theexpression of HsmiPEP155 increases the expression of HsmiR155.

The mutated pri-miR171b is therefore incapable ofproducing miPEP171b1. The error bar corresponds to the standard error ofthe mean (number of individuals=30). It is noted that the absence oftranslation of miPEP171b1 leads to a marked decrease in the accumulationof miR171b.

FIG. 21. Effects of overexpression of MtmiPEP171b1 on the expression ofMtmiR171b demonstrated in the model plant Nicotiana benthamiana.

The error bar corresponds to thestandard error of the mean (number of individuals=30). It is noted thatthe expression of MtmiPEP171b1 increases the expression of MtmiR171b,and this effect is dependent on the translation of MtmiORF171b toMtmiPEP171b1.

FIG. 22. Effects of AtmiPEP165a on accumulation of AtmiR165a and of itstarget genes (PHA VOL UTA: PHV, PHABOL USA: PHB and REVOLUTA: REV).

The treatment of plants with higher and higher concentrations ofAtmiPEP165a demonstrates a dose-dependent effect of the accumulation ofAtmiR165a and the negative regulation of its target genes as a functionof the quantity of AtmiPEP165a.

DETAILED DESCRIPTION OF THE INVENTION

In a first step, the process for detecting and identifying amicropeptide therefore consists of detecting, on the primary transcriptof a microRNA, the existence of an open reading frame potentiallyencoding a peptide.

For its part, the second step makes it possible to characterize saidpeptide, i.e. to determine whether said peptide corresponds to a peptidereally produced in the cell, by searching for an effect of said peptideon the accumulation of said microRNA.

In order to demonstrate an effect of the peptide on the accumulation ofthe microRNA, a large quantity of peptide is introduced into a firstcell expressing said microRNA. The accumulation of the microRNA in thisfirst cell is then measured and compared with the accumulation of themicroRNA in a second cell identical to the first, but not containingsaid peptide.

Observation of a variation of the quantities of microRNA between thecells in the presence and in the absence of the peptide thus indicates(i) that there is a peptide encoded on the primary transcript of saidmicroRNA, (ii) that the sequence of this peptide is encoded by the openreading frame identified on the primary transcript of said microRNA, and(iii) that said peptide has an effect on the accumulation of saidmicroRNA.

The invention is therefore based on the unexpected double observationmade by the inventors that, on the one hand, there are open readingframes that are able to encode micropeptides present on the primarytranscripts of microRNAs, and on the other hand that said micropeptidesare capable of modulating the accumulation of said microRNAs.

In particular, the invention relates to a process for detecting andidentifying a micropeptide (miPEP) encoded by a nucleotide sequencecontained in the sequence of the primary transcript of a microRNA,comprising:

-   -   a) a step of detecting an open reading frame from 15 to 303        nucleotides in length contained in the sequence of the primary        transcript of said microRNA, then    -   b) a step of comparison between:        -   the accumulation of said microRNA in a specified eukaryotic            cell expressing the primary transcript of said microRNA,        -    in the presence of a peptide encoded by a nucleotide            sequence that is identical or degenerate relative to that of            said open reading frame, said peptide being present in the            cell independently of transcription of the primary            transcript of said microRNA, and        -   the accumulation of said microRNA in a eukaryotic cell of            the same type as the aforesaid specified eukaryotic cell            expressing the primary transcript of said microRNA,        -    in the absence of said peptide,            in which a modulation of the accumulation of said microRNA            in the presence of said peptide relative to the accumulation            of said microRNA in the absence of said peptide indicates            the existence of a micropeptide encoded by said open reading            frame.

In the invention, the terms “microRNA”, “non-coding microRNA” and“miRNA” are equivalent and may be used interchangeably. They definesmall molecules of RNA of about 21 nucleotides, which are not translatedand do not lead to a peptide or a protein. However, in this mature form,the microRNAs perform a function of regulation of certain genes viapost-transcriptional mechanisms, for example by means of the RISCcomplex.

The primary transcript of the microRNA or “pri-miRNA” corresponds to theRNA molecule obtained directly from transcription of the DNA molecule.Generally, this primary transcript undergoes one or morepost-transcriptional modifications, involving for example a particularstructure of the RNA or cleavage of certain portions of the RNA bysplicing phenomena, and which lead to the precursor form of the microRNAor “pre-miRNA”, then to the mature form of the microRNA or “miRNA”.

The terms “micropeptides” and “miPEPs” (microRNA encoded PEPtides) areequivalent and may be used interchangeably. They define a peptide thatis encoded by an open reading frame present on the primary transcript ofa microRNA, and which is capable of modulating the accumulation of saidmicroRNA.

In view of the above definitions, it is important to distinguish on oneside, the miRNA which does not encode any peptide and on the other side,the primary transcript of such a miRNA which may encode a miPEP.

This distinction derives from the teaching of the invention and isoriginal in view of the current knowledge about miRNAs.

The micropeptides within the meaning of the present invention are not tobe understood as necessarily being small peptides, as “micro” does notcorrespond to the size of the peptide.

Taking into account the degeneracy of the genetic code, one and the samemicropeptide is or may be encoded by several nucleotide sequences.Nucleotide sequences of this kind, differing from one another by atleast one nucleotide but encoding one and the same peptide, are called“degenerate sequences”.

The terms “open reading frame” or “ORF” are equivalent and may be usedinterchangeably. They correspond to a nucleotide sequence in a DNA orRNA molecule that may potentially encode a peptide or a protein: saidopen reading frame begins with a start codon (the start codon generallyencoding a methionine), followed by a series of codons (each codonencoding an amino acid), and ends with a stop codon (the stop codon notbeing translated).

In the invention, the ORFs may be called specifically “miORFs” when theyare present on the primary transcripts of microRNA.

The miORFs as defined in the particular invention may have a size from12 to 303 nucleotides and may encode peptides from 3 to 100 amino acids.

In particular, the miORFs as defined in the invention may have a sizefrom 15 to 303 nucleotides. As an amino acid is encoded by a codon of 3nucleotides, the miORFs from 15 to 303 nucleotides encode miPEPS from 4to 100 amino acids.

In particular, the miORFs have a size of:

15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 47, 51, 54, 57, 60, 63, 66,69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105, 108, 111, 114,117, 120, 123, 126, 129, 132, 135, 138, 141, 144, 147, 150, 153, 156,159, 162, 165, 168, 171, 174, 177, 180, 183, 186, 189, 192, 195, 198,201, 204, 207, 210, 213, 216, 219, 222, 225, 228, 231, 234, 237, 240,243, 246, 249, 252, 255, 258, 261, 264, 267, 270, 273, 276, 279, 282,285, 288, 291, 294, 297, 300 or 303 nucleotides, and encode respectivelymiPEPs having a size of:4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22,23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40,41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58,59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76,77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94,95, 96, 97, 98, 99 or 100 amino acids.

In the invention, “accumulation” means the production of a molecule,such as a microRNA or a micropeptide, in the cell.

Thus, “modulation” of the accumulation of a molecule in a cellcorresponds to a modification of the quantity of this molecule presentin the cell.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which the modulation of theaccumulation of said microRNA is a decrease or an increase in theaccumulation of said microRNA, in particular an increase.

A “decrease in the accumulation” corresponds to a decrease in thequantity of said molecule in the cell.

Conversely, an “increase in the accumulation” corresponds to an increasein the quantity of said molecule in the cell.

In an advantageous embodiment, the invention relates to a process fordetecting and identifying a miPEP as defined above, in which themodulation of the accumulation of said microRNA is an increase in theaccumulation of said microRNA.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which the presence of saidpeptide in the cell results from:

-   -   the introduction of a nucleic acid encoding said peptide into        the cell, or    -   the introduction of said peptide into the cell.

In order to characterize a miPEP, it is necessary to have a cellularmodel expressing a microRNA in which said peptide to be tested ispresent. For this, it is possible to introduce a peptide into the cell,either by bringing the cell into contact with said peptide, or byintroducing a nucleic acid encoding said peptide into the cell, and thisnucleic acid will then be translated into peptide within the cell.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said open reading framein step a) is contained in the 5′ or 3′ portion of said primarytranscript of the microRNA, preferably in the 5′ portion.

The 5′ or 3′ portions of the primary transcript of the microRNAcorrespond to the terminal portions of the RNA molecule that are cleavedduring maturation of the microRNA.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said microRNA is presentin a wild-type plant cell. In the invention, a wild-type plant cellcorresponds to a plant cell that has not been genetically modified byhumans.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said microRNA is presentin a wild-type animal cell, and in particular a wild-type human cell ora wild-type Drosophila cell.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said specified eukaryoticcell and said eukaryotic cell of the same type as the aforesaidspecified eukaryotic cell, used in step b, are plant cells of acruciferous plant such as Arabidopsis thaliana, of a leguminous plantsuch as Glycine max (soya), Medicago truncatula and Medicago sativa(alfalfa) or of a plant of the Solanaceae family such as Nicotianabenthamiana (tobacco), Solanum tuberosum (potato), Solanum lycopersicum(tomato) or Solanum melongena (aubergine).

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said specified eukaryoticcell and said eukaryotic cell of the same type as the aforesaidspecified eukaryotic cell, used in step b, are plant cells, preferablycells of Medicago truncatula, Nicotiana benthamiana or Arabidopsisthaliana.

In an embodiment, the invention relates to a process for detecting andidentifying a miPEP as defined above, in which said specified eukaryoticcell and said eukaryotic cell of the same type as the aforesaidspecified eukaryotic cell, used in step b, are animal cells, preferablyhuman cells or Drosophila cells.

In the process for detecting and identifying a micropeptide as definedabove, after identifying an ORF that is able to encode a peptide on theprimary transcript of a microRNA, it is necessary to have a cellularmodel having said microRNA and said peptide, so as to be able todemonstrate a possible effect of the peptide on said microRNA.

Two options are therefore conceivable:

-   -   the cellular model in which the miORF has been identified and        that in which the effect of the peptide on the miRNA has been        demonstrated are identical, or    -   the cellular model in which the miORF has been identified and        that in which the effect of the peptide on the miRNA has been        demonstrated are different.

In the first option, the cellular model used for observing an effect ofthe peptide is the same as that in which the primary transcript of saidmicroRNA was isolated. In this cellular model, the specified eukaryoticcells contain said microRNA naturally and only the peptide

to be tested has to be introduced into these cells. In this context,said microRNA is qualified as “of endogenous origin” as it existsnaturally in the cells. Nevertheless, other copies of a microRNA ofendogenous origin may be added to a cell, for example by introducing avector encoding said microRNA of endogenous origin into the cell.

In the second option, the cellular model used for observing an effect ofthe peptide is different from that in which the primary transcript ofsaid microRNA was isolated. In this cellular model, the specifiedeukaryotic cells contain neither the microRNA, nor the peptide to betested. These two elements must therefore be introduced into thesecells. In this context, said microRNA is qualified as “of exogenousorigin” as it does not exist naturally in the cells.

In the invention, the expressions “of endogenous origin” and “ofexogenous origin” are used for distinguishing said microRNAs and/or thegenes of different species, in view of the conservation of the sequencesbetween species.

said miPEP naturally present in said plant being a peptide of 4 to 100amino acids the sequence of which is encoded by an open reading framelocated on the primary transcript of a miRNA, said miPEP being capableof modulating the accumulation of said miRNA in said plant, said miRNAregulating the expression of at least one gene involved in thedevelopment of the vegetative or reproductive parts of the plant, inparticular the roots, stem, leaves or flowers.

The inventors have surprisingly found that the use of peptides thesequence of which comprises or consists of a sequence identical to thatof miPEPs encoded on the primary transcripts of miRNAs makes it possibleto promote the growth of the plants.

In the invention, the term “plant” refers generally to the whole or partof a plant irrespective of its stage of development (including the plantin the form of a seed or a young shoot), to one or more organs of theplant (for example the leaves, roots, stem, flowers), to one or morecells of the plant, or to a cluster of cells of the plant.

In the invention, the term “growth” refers to the development of thewhole or part of a plant over time. The growth of the plant may thus bedetermined and quantified by monitoring developmental parametersobservable for certain parts, cells or organs of the plant, such as theleaves, roots, stems or flowers.

Non-limitatively, the parameters for determining and quantifying thegrowth of a plant may in particular be:

-   -   the size, surface area, volume, mass and the number of leaves,    -   the size and number of flowers,    -   the size of the stem (or spike),    -   the length and number of roots,    -   the earliness of germination,    -   the earliness of budding,    -   the earliness of floral induction (or floral transition),    -   or also the number of cells.

In the case of leguminous plants, plant growth may also be linked to therate of nodulation, or also to the size and number of nodules on theroots.

Moreover, in the invention, the expression “promote plant growth”, or“improve plant growth”, indicates:

-   -   either an acceleration of development (such as for example a        larger leaf size for a plant at a given point in time relative        to a reference plant),    -   or an increase in development (such as for example a larger leaf        size for a plant that cannot be attained by a reference plant),    -   or an acceleration and an increase in the development of the        plant.

It is important to note that the use according to the invention has theadvantage of being ecological, in comparison with the chemical methodsused conventionally in horticulture or in agriculture, as the miPEP is apeptide that is present naturally in the plant.

The invention also relates to the use of a miPEP introduced into a plantfor promoting its growth,

said miPEP introduced being a peptide comprising, or consisting of, asequence identical to that of a miPEP naturally present in said plant,said miPEP naturally present is a peptide of 4 to 100 amino acids, thesequence of which is encoded by an open reading frame located at 5′ onthe primary transcript of a miRNA,said miPEP being capable of modulating the accumulation of said miRNA insaid plant,said miRNA regulating the expression of at least one gene involved inthe development of the vegetative or reproductive parts of the plant, inparticular the roots, stem, leaves or flowers, the sum total of thequantity of said miPEP introduced and that of said miPEP naturallypresent being strictly greater than the quantity of said miPEP naturallypresent.

In the invention, the expression “miPEP introduced” refers to a miPEPintroduced into the plant artificially as opposed to the “miPEP presentnaturally in the plant”. The introduction of a miPEP into the planttherefore involves a technological step, which is not a naturalphenomenon and corresponds neither to crossing, nor to selection.

The miPEP introduced may be either a peptide produced outside of theplant (for example an isolated and/or purified peptide, a syntheticpeptide or a recombinant peptide), or a peptide produced in the plantfollowing the non-natural introduction of a nucleic acid encoding saidmiPEP into said plant.

The plant into which the miPEP has not been introduced has a basalquantity of said miPEP, which corresponds to the quantity of said miPEPnaturally present. The use of a miPEP comprising, or consisting of, asequence identical to that of said miPEP leads to an increase in thetotal quantity of miPEP, which modulates the accumulation of the miRNAthe primary transcript of which contains the sequence encoding saidmiPEP.

Moreover, the miPEP introduced is present in the plant and itsintroduction has no impact on its stability.

EXAMPLES A: Analysis of the miPEPS in Plants Example 1 Characterizationin the Model Plant Medicago truncatula

a) Identification and Characterization of MtmiPEP171b1 (miPEP171b1Identified in Medicago truncatula)

This microRNA is expressed in the meristematic region of the roots. Theoverexpression of this microRNA in particular leads to a reduction inthe expression of the genes HAM1 (Accession No. MtGI9-TC114268) and HAM2(Accession No. MtGI9-TC120850) (FIG. 1A), as well as to a reduction inthe number of lateral roots (FIG. 1B).

The sequence of the primary transcript of MtmiR171b was determined usingthe RACE-PCR technique. Analysis of the sequence of the primarytranscript made it possible to identify the presence of severalcompletely unexpected small open reading frames (sORFs). These sORFswere called miORFs for “microRNA ORFs”. These miORFs potentially encodeshort peptides, from about 4 to 100 amino acids. No significant homologyrelating to these miORFS was found in the databases.

The overexpression of the first miORF, called MtmiORF171b, leads to anincrease in the accumulation of MtmiR171b and a reduction in theexpression of the HAM1 and HAM2 genes (see FIG. 2A), as well as to areduction in the number of lateral roots (FIG. 2B), as was alreadyobserved in the overexpression of MtmiR171b.

In order to determine whether MtmiORF171b leads to the real productionof a peptide and whether the regulatory function observed above isindeed carried by said peptide, a synthetic peptide, the sequence ofwhich is identical to that potentially encoded by MtmiORF171b, wasapplied on the roots of Medicago truncatula. Application of this peptideleads to the phenotype already observed above in the overexpression ofMtmiORF171b, i.e. it leads to an increase in the accumulation ofMtmiR171b and a reduction in the expression of the HAM1 and HAM2 genes(see FIG. 3A), as well as a reduction in the number of lateral roots(FIG. 3B).

The results of these experiments demonstrate that MtmiORF171b encodes apeptide capable of modulating the accumulation of MtmiR171b, and theexpression of the target genes of MtmiR171b: HAM1 and HAM2. Said peptidehas been called MtmiPEP171b1 (“miPEP” corresponding to microRNA encodedPEPtide).

Moreover, MtPEP171b1 leads to an increase in the accumulation ofMtmiR171b (FIG. 104A) and of pre-MtmiR171b (FIG. 4B).

b) Specificity of miPEP171b1

The expression of different microRNA precursors of Medicago truncatula(MtmiR171b SEQ ID NO: 319, MtmiR169 SEQ ID NO: 367, MtmiR169a SEQ ID NO:368, MtmiR171a SEQ ID NO: 369, MtmiR171 h SEQ ID NO: 370, MtmiR393a SEQID NO: 371, MtmiR393b SEQ ID NO: 372, MtmiR396a SEQ ID NO: 373 andMtmiR396b SEQ ID NO: 374) was determined and compared between controlplants and plants in which MtmiORF171b encoding MtmiPEP171b1 wasoverexpressed (FIG. 5A), or between control plants and plants grown onculture medium containing MtmiPEP171b1 (FIG. 5B).

The results obtained indicate that MtmiPEP171b1 only leads to anincrease in the accumulation of MtmiR171b and not of the other miRNAs,which indicates that a miPEP only has an effect on the microRNA fromwhich it is derived.

c) Localization of miPEP171b1

Moreover, the immunolocalization of miPEP171b1 in the roots of M.truncatula reveals the presence of miPEP171b1 in the lateral rootinitiation sites, showing a co-localization between the microRNA and thecorresponding miPEP (FIG. 28).

Example 2 Characterization in the Model Plant of Tobacco a) Conservationof the Mechanism in Tobacco

In order to determine whether the mechanism of regulation of themicroRNAs is conserved in other plant species, the regulation ofMtmiR171b by MtmiPEP171b1 was tested in a different cellular model. Forthis, MtmiR171b and MtmiPEP171b1 were introduced into tobacco leaves.

The accumulation of MtmiR171b was measured in tobacco leaves transformedin order to express MtmiR171b of Medicago truncatula starting fromwild-type pri-miRNA capable of producing MtmiPEP171b1, or starting froma mutated version of pri-miRNA incapable of producing MtmiPEP171b1 (inwhich the start codon ATG of MtmiORF171b has been replaced with ATT)(FIG. 6 and FIG. 20). Absence of translation of MtmiPEP171b1 leads to amarked decrease in the accumulation of MtmiR171b.

The accumulation of pre-MtmiR171b was measured in tobacco leavestransformed in order to express MtmiR171b of Medicago truncatula alone(control), or additionally expressing the wild-type MtmiORF171b ofMedicago truncatula (35SmiPEP171b1 ATG), or a mutated version ofMtmiORF171b in which the start codon ATG has been replaced with ATT(35SmiPEP171b1 ATT) (FIG. 7 and FIG. 21). The expression of MtmiORF171bleads to an increase in the accumulation of pre-miR171b, and thisaccumulation of pre-miR171b depends on the translation of MtmiORF171b tomicropeptide.

Moreover, in the tobacco leaves transformed in order to expressMtmiR171b of Medicago truncatula, untreated or treated by spraying withMtmiPEP171b1 (0.1 μM) for the first time 12 h before sampling and then asecond time 30 minutes before sampling, it was observed thatMtmiPEP171b1 may be used directly in peptide form by foliar sprayings(FIG. 8).

Moreover, it was observed in tobacco (as in Medicago truncatula) thatthe MtmiPEP171b1 leads to an increase in the accumulation of MtmiR171b(FIG. 9A) and of pre-MtmiR171b (FIG. 9B), but reduces the accumulationof pri-MtmiR171b (FIG. 9C).

Taken together, these results indicate that the mechanism of regulationof the microRNAs and of their target genes under the control of miPEPsis conserved between the species.

b) Intracellular Localization of MtmiPEP171b1

Tobacco leaves were transformed in order to overexpress MtmiPEP171b1 ofMedicago truncatula fused with a fluorescent protein (GFP) (FIG. 10).The results obtained indicate that the miPEP is localized in smallnuclear bodies.

c) Identification of miPEPS from Databases

Genomic databases of plants were searched for the presence of openreading frames within primary transcripts of 70 miRNAs, and 101 miORFscapable of encoding a miPEP were identified.

At present, AtmiPEP165a and AtmiPEP319a2, identified in Arabidopsisthaliana, have already been characterized. The experiments conducted inthe model plant of tobacco made it possible to demonstrate that theoverexpression of AtmiORF165a or of AtmiORF319a leads to an increase inthe accumulation of AtmiR165a or of AtmiR319a respectively (FIG. 11).

miR165a regulates transcription factors such as Revoluta, Phavoluta andPhabulosa. miR319 regulates genes of the TCP family.

Example 3 Characterization in the Arabidopsis thaliana Model PlantExample 3A AtmiPEP165a

Regarding AtmiPEP165a, it has been demonstrated in vivo in Arabidopsisthaliana that treatment with AtmiPEP165a leads to a phenotype withgreatly accelerated root growth (FIG. 12).

Moreover, treatment of plants with higher and higher concentrations ofmiPEP165a shows a dose-dependent effect on the accumulation of miR165aand the negative regulation of its target genes (PHAVOLUTA: PHV,PHABOLUSA: PHB and REVOLUTA: REV) as a function of the amount ofmiPEP165A (see FIG. 22).

Example 3B AtmiPEP164a

Regarding AtmiPEP164a, this was synthesized and was used forinvestigating an increase in the accumulation of miR164a in roots of A.thaliana treated with the synthetic peptide.

Northern blot analyses indicate that treatment of the plant with thepeptide miPEP164a leads to an increase in the accumulation of miR164a(FIG. 23).

It has also been demonstrated in vivo in Arabidopsis thaliana thattreatment of the plant with AtmiPEP164a increases plant growthsignificantly (FIG. 24).

Example 3C AtmiPEP165a

Regarding AtmiPEP165a, this was synthesized and was used forinvestigating an increase in the accumulation of miR165a in roots of A.thaliana treated with the synthetic peptide.

Northern blot analyses indicate that treatment of the plant with thepeptide miPEP165a leads to an increase in the accumulation of miR165a(FIG. 25).

Example 4C AtmiPEP319a1

Regarding AtmiPEP319a1, this was also synthesized and was used forinvestigating an increase in the accumulation of miR319a in roots of A.thaliana treated with the synthetic peptide.

Analyses by qRT-PCR show that the overexpression of AtmiPEP319a1 leadsto an increase in the accumulation of miR319a (FIG. 26).

It was also demonstrated in vivo in Arabidopsis thaliana that treatmentof the plant with AtmiPEP319a1 increases plant growth significantly(FIG. 27).

Material and Methods Biological Material

The surface of seeds of M. truncatula was sterilized and they were leftto germinate on agar plates for 5 days at 4° C. in the dark. The youngshoots were then grown on 12-cm square plates filled with Fahraeusmedium without nitrogen and containing 7.5 μM phosphate (Lauressergueset al., Plant J., 72(3): 512-22, 2012). The lateral roots were countedevery day. In pots, the plants were watered every other day withmodified Long Ashton medium with low phosphorus content (Balzergue etal., Journal of Experimental Botany, (62)1049-1060, 2011).

The peptides were synthesized by Eurogentec or Smartox-Biotech.MtmiPEP171b1 was resuspended in a solution of 40% water/50%acetonitrile/10% acetic acid (v/v/v), and the other peptides wereresuspended in water.

The leaves were watered by spraying with the peptides using peptidesolutions at different concentrations (0.01, 0.1, 1 μM), firstly 12 hbefore sampling and then a second time min before sampling.

Reverse Transcription of the microRNAs

The RNA was extracted using the reagent Tri-Reagent (MRC) according tothe manufacturer's instructions, except for precipitation of the RNA,which was carried out with 3 volumes of ethanol. The eversetranscription of the RNA was carried out using the specific stem-loopprimer RTprimer171b in combination with hexamers for performing thereverse transcription of RNA of high molecular weight.

In brief, 1 μg of RNA was added to the stem-loop primer MIR171b (0.2μM), the hexamer (500 ng), the buffer RT (1×), the enzyme SuperScriptReverse transcriptase (SSIII) (one unit), the dNTPs (0.2 mM each), DTT(0.8 mM) in a final reaction mixture of 25 μl. In order to carry out thereverse transcription, a reaction of pulsed reverse transcription wasperformed (40 repetitions of the following cycle: 16° C. for 2 minutes,42° C. for one minute and 50° C. for one second, followed by a finalinactivation of the reverse transcription at 85° C. for 5 minutes).

Analyses by Quantitative RT-PCR (qRT-PCR)

The total RNA was extracted from roots of M. truncatula or from tobaccoleaves using the extraction kit RNeasy Plant Mini Kit (Qiagen). Thereverse transcription was performed using the reverse transcriptaseSuperScript II (Invitrogen) starting from 500 ng of total RNA. Threerepetitions (n=3) were carried out, each with two technical repetitions.Each experiment was repeated from two to three times. The amplificationsby qPCR were carried out using a LightCycler 480 System thermocycler(Roche Diagnostics) by the method described in Lauressergues et al.(Plant J., 72(3): 512-22, 2012).

Statistical Analyses

The mean values of the relative expression of the genes or of theproduction of lateral roots were analysed using the Student test or theKruskal-Wallis test. The error bars represent the SEM (Standard Error ofthe Mean). The asterisks indicate a significant difference (p<0.05).

Plasmid Constructs

The DNA fragments of interest were amplified with Pfu polymerase(Promega). The DNA fragments were cloned using the XhoI and NotI enzymesinto a pPEX-DsRED plasmid for an overexpression under the control of theconstitutive strong promoter 35S, and using the KpnI-NcoI enzymes into apPEX GUS plasmid for the reporter genes, by the method described inCombier et al. (Genes & Dev, 22: 1549-1559, 2008).

For the miPEPs 165a and 319a, the corresponding miORFs were cloned intopBIN19 by the method described in Combier et al. (Genes & Dev, 22:1549-1559, 2008).

Transformation of the Plants

The composite plants having roots transformed with Agrobacteriumrhizogenes were obtained by the method described in Boisson-Dernier etal. (Mol Plant-Microbe Interact, 18: 1269-1276, 2005). The transformedroots were verified and selected by observations of DsRED with abinocular fluorescence magnifier. The control roots correspond to rootstransformed with A. rhizogenes not containing the pPEX-DsRED vector.Transformation of the tobacco leaves was carried out by the methoddescribed in Combier et al. (Genes & Dev, 22: 1549-1559, 2008).

Northern Blot

Northern blot analysis was carried out according to the protocoldescribed in Lauressergues et al. Plant J, 72(3): 512-22, 2012.

The biological samples were homogenized in a buffer containing 0.1 M ofNaCl, 2% of SDS, 50 mM of Tris-HCl (pH 9), 10 mM of EDTA (pH 8) and 20mM of mercaptoethanol, and the RNA was extracted twice with aphenol/chloroform mixture and was precipitated with ethanol.

The RNA was loaded on PAGE 15% gel and transferred to a nylon membrane(HybondNX, Amersham). RNA was hybridized with a radioactiveoligonucleotide probe labelled at its end, in order to detect the RNA U6or for miR164a.

The hybridizations were carried out at 55° C. The hybridization signalswere quantified using a phosphorimager (Fuji) and normalized with thesignal of the specific probe of RNA U6.

Histochemical Labelling

Labelling with GUS was carried out by the method described in Combier etal., (Genes & Dev, 22: 1549-1559, 2008). The samples were observed witha microscope (axiozoom).

Immunolocalization

Roots or plantlets of tissues of Medicago were fixed for 2 hours in 4%formal (v/v) with 50 mM of phosphate buffer (pH 7.2), and then embeddedin agarose LMP 5% in water (with a low melting point). Thin sections(100 μm) were obtained and were placed in Pbi (phosphate buffer forimmunology) on Teflon-coated slides, blocked in Pbi, 2% Tween and 1% ofbovine serum albumin for 2 hours (PbiT-BSA), then labelled overnight (12h) at 4° C. with the primary antibody diluted in BSA-PbiT. The sectionswere washed with PBiT and incubated at ambient temperature for 2 h witha secondary antibody diluted in PbiT-BSA. The slides were then washed inPbi for 30 min and mounted in Citifluor (mounting medium). The primaryantibodies and the dilutions were as follows: 1716a (1:500, v/v). Thesecondary antibody was a goat anti-rabbit IgG antibody coupled to theAlexa Fluor 633 fluorescent probe (Molecular Probes), and was used at adilution of 1:1000 (v/v).

B: Analysis of the miPEPs in Animals Example 4 Identification ofCandidate miPEPs in Drosophila

A first study carried out by RACE-PCR in the model animal Drosophilamelanogaster shows the existence of miRNAs that are expressed duringembryogenesis, miR1 and miR8.

As in the plants, miORFs were identified in each of the two miRNAsstudied. For example, miR8, known for its role in the regulation ofgrowth in insects, has a miORF potentially encoding miPEP8.

Regarding DmmiR1 (identified in Drosophila melanogaster), it has twoDmmiORFs potentially encoding DmmiPEP1a and DmmiPEP1b.

A phylogenetic analysis shows evolutionary conservation of the presenceof the miORFs among the dozen Drosophila species analysed, i.e. sincetheir divergence more than 60 million years ago (FIG. 13).

Moreover, the miPEPs identified in Drosophila have several similaritieswith the plant miPEPs. If their primary sequence and therefore theirsize evolve rapidly between species, a reduced size (from 32 to 104 AA)is found, as well as strong conservation for a basic overall charge (pHifrom 9.5 to 12) (FIG. 14).

Taken together, these results therefore indicate the existence ofregulatory miPEPs, encoded by the primary transcript of the microRNAs,over a broad spectrum of eukaryotic species. These discovered peptidesrepresent an as yet unexplored reservoir of natural molecules that mayregulate a variety of fundamental biological functions, both in plantsand in animals.

Cells of Drosophila melanogaster

S2 cells are cultured in a T75 flask in 12 mL of Schneider's medium(GIBCO), containing 1% of penicillin 100 U/mL and streptavidin 100 mg/mL(Sigma) and 10% of decomplemented foetal calf serum (30 min at 56° C.).

The transient transfections are carried out using the FuGENE® HDtransfection kit (Roche), according to the recommendations.Conventionally, 1.5 million S2 cells, previously seeded in 6-well plates(3 ml of medium per well), are transfected with 250 ng of total plasmidDNA. The DNA is brought into contact with the Fugene (3 μl) in 100 μl ofOPTIMEM (GIBCO). After 20 minutes, the transfection reagent formed isbrought into contact with the cells in the culture medium. The RNA ofthe cells is extracted 66 h after transfection.

C: Characterization of miPEPs in Humans Example 5 Characterization ofHsmiPEP155

The DNA fragments of interest (HsmiPEP155 and the mutated miPEP) weresynthesized or amplified by PCR using specific primers, and then clonedusing the enzymes XhoI and NotI into a pUAS plasmid permitting theiroverexpression by means of the GAL4 transcription factor, the expressionof which is controlled by a constitutive strong promoter.

The different constructs were produced either by PCR amplification ongenomic DNA of HeLa cells, or by RT-PCR on total RNAs of L428 humancells. The amplified PCR fragments are digested with the HindIII/EcoRIrestriction enzymes and then cloned into the vector pcDNA3.1. The DH5αstrain of Escherichia coli is electroporated and then cultured on asolid medium (2YT+agar+ampicillin). The plasmid DNA from differentclones is then prepared and sequenced for verification. The constructsare then prepared using the QIAfilter Plasmid Midi kit (QIAGEN) andstored at −20° C.

The HeLa cells (established tumour line, ATCC CCL-2.2) are cultured in a6-well plate in complete medium [(DMEM (1×)+Glutamax+4.5 g/L glucosewithout pyruvate+1× penicillin/streptomycin+1 mM Na-pyruvate+10% calfserum] and placed in an incubator at 37° C. and 5% CO₂.

The cells are transfected when they are at 50% confluence. At the startof the experiment, the complete medium containing the antibiotics isreplaced with complete medium without antibiotics.

For each well, a mix A [250 μl of Optimem (+Glutamax) (Gibco)+2 μg ofDNA] and a mix B [250 μl of Optimem+4 μl of Lipofectamine 2000(Invitrogen)] is prepared, and left for 5 min at ambient temperature.Then mix B is mixed dropwise into mix A, and left to incubate for 25 minat ambient temperature. The mixture is then deposited dropwise into thewell. 4-5 hours later, the medium is changed and replaced with completemedium with antibiotics. 48 hours after transfection, the cells arestopped. The medium is aspirated and discarded; the cells are rinsedwith PBS 1×. It is then possible to store the cells at −20° C. orextract the total RNAs directly.

For each well, the RNAs are extracted by depositing 1 ml of Tri-Reagent(Euromedex) on the cells. The Tri-reagent is aspirated and returnedseveral times so that the cells are lysed correctly, and then it istransferred into a 1.5-ml tube. 0.2 ml of water-saturated chloroform isadded. It is mixed by vortexing, then left for 2 to 3 minutes at ambienttemperature. It is centrifuged for 5 minutes at 15300 rpm and at 4° C.The aqueous phase is precipitated from 0.5 ml of isopropanol afterincubation for 10 minutes at ambient temperature and centrifugation for15 minutes at 15300 rpm and at 4° C. The supernatant is discarded andthe pellet is rinsed with 1 ml of 70% ethanol, with centrifugation for 5minutes at 15300 rpm at 4° C. The supernatant is again discarded and thepellet is dried for a few minutes in the air. For best-possible removalof the genomic DNA potentially remaining, the RNAs are treated withDNase. For this, the pellet is resuspended in 170 μl of ultra-purewater, 20 μl of DNase buffer 10× and 10 μl of RQ1 RNase-free DNase andheld at 37° C. for 30 minutes. Then 20 μl of SDS10% and 5 μl ofproteinase K (20 mg/ml) are added over 20 minutes at 37° C.

A last phenol extraction is carried out with 225 μl of aphenol/H₂O/chloroform mixture, and centrifuged for 5 minutes at 15300rpm at 4° C.

The aqueous phase is then precipitated from 20 μl of 3M sodium acetateand 600 μl of 100% ethanol for 20 minutes at −80° C. Then it iscentrifuged for 15 min at 4° C. at 15300 rpm. The supernatant isdiscarded. The pellet is rinsed in 1 ml of 70% ethanol, centrifuged for5 min at 15300 rpm at 4° C., the supernatant is discarded again and thepellet is left to dry for some minutes in the air.

The pellet is then taken up in 15-20 μl of ultra-pure water and the RNAsare assayed.

10-15 μg of total RNAs is then analysed by Northern blot on 15%acrylamide gel [solution of acrylamide/40% bis-acrylamide, ratio 19:1],7M urea in TBE 1×. Migration is carried out at 400V, in TBE1× asmigration buffer, after preheating the gel. The RNAs are thenelectro-transferred onto a Biodyne Plus 0.45 μm nylon membrane, for 2hours, at 1V and 4° C. in a transfer tank. At the end of transfer, themembrane is irradiated with UV at 0.124 J/cm². The membrane is thenpre-hybridized in a buffer 5×SSPE, 1×Denhardt's, 1% SDS and 150 μg/ml ofyeast tRNA, for 1 hour at 50° C. in a hybridization oven. Then thenucleotide probe is added, labelled at 5′ with ^(γ)-³²P-ATP (0.5 to1·10⁶ cpm/ml of hybridization buffer) and is hybridized overnight at 50°C. The membrane is then washed twice in 0.1×SSPE/0.1% SDS at ambienttemperature and exposed in an autoradiography cassette containing aBioMax HE screen (Kodak) and a BioMax MS film (Kodak), in order todetect a microRNA, for 24-48 hours, at −80° C.
